A UNITED STATES PATENT OFFIC.

CHARLES E. NEBEL, 0F GLADSTONE, MICHIGAN.

WRENCH.

T 0 all whom it may concern:

Be it known that I, CHAnLns E. NEBEL, a citizen of the United States,residing at Gladstone, in the county of Delta and State of Michigan,have invented certain new and useful Improvements in renches, of whichthe following is a specification, reference being had therein totheaccompanying drawin s. i

lhis invention relates to wrenches and has for its object the productionof a simple and efficient pipe wrench which may be con venientlyadjusted to different size pipes, for threading one pipe into anotherpipe or into a threaded joint adapted to receive the same.

Another object of thisinvention is the production of a simple andefiicient means for gripping the chain and holding the same ti "htlyaround a pipe.

Vith these and other objects in view this invention consists of certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the drawings:

Figure 1 is a View in side elevation of a portion of the wrench showingthe same as it appears in operation.

Fig. 2 is a longitudinal sectional view through the wrench.

Fig. 3 is a view in end elevation of the wrench showing the grippingchain in section.

Fig. 1 is a bottom plan view of the.

wrench.

Fig. 5 is a front view, in elevation, of the chain gripping link.

By referring to the drawings it will be seen that 1 designates thehandle of the wrench which may be made of any material desired such aswood and the like and this handle 1 is provided with a reduced shank 2over which reduced shank 2 fits a metallic casing 3. Thethandle 1 isprovided with an abutment shoulder 4 against which fits the casing 3.This casing is firmly held upon the shank portion 2 by means of asecuring bolt 5 as shown clearly in Fig. 2 of the drawings.

The casing 3 is provided with a thickened upper face 6 having aplurality of trans versely extending notches? formed therein.

(A chain gripping link 8 is adapted to fit within one of these notches 7and this chain engaging link 8 is provided. with a chain Specificationof Letters Patent.

gripping socket 9 formed therein for receiving the end link 10 of thechain 11. The link 8 is adapted to fit over the casing 3 as shown inFigs. 2 and 3 of the drawings and the shoulder portions 8 bears againstthe bottom of the casing 3 for preventing the link 8 from moving towardthe inner end of the handle 1, when the handle 1 raised, but will pressupon the handle 1. The chain 11 is adapted to pass around the pipe 12and the free end of this chain 11 adapted to fit within the chaingripping SOLlIQt 13 formed in the chain gripping or grab link 14. Anyone of the vertically extending links 15 of the chain 11 is adapted tofit in this socket 13 and the transversely extending links 15 of thechain will firmly hold the chain against longitudinal movement throughthe link 1 1-. The vertically extending links 15 of the chain willfirmly be held within the notch 13 by some of said links 15 resting uponthe corner 1'? of the casin 6 thereby preventing the chain fromaccidentally falling out of the 110th or socket 13. The casing 3 isprovided with an aperture 18 formed therein which registers with asocket 19 formed in the shank 2 for receiving the transversely extendingportion 20 of the link 14 thereby pivotally connecting this link 1 1with the shank 2 of the handle 1. The transversely extending portion 20of the link 14: is firmly held within the socket 19 by means of anadjustable plate 21 which overhangs the socket 19 and this plate 21 isprovided with a longitudinally extending slot 22 through which slot passthe bolts 23 for holding the plate 21 in a set position and againstsliding movement upon the casing 3. j

The end of the handle 1 is adapted to set squarely against the pipe 12and the chain 11 passes around the pipe 12 in a taut condition, one endbeing secured to the link 8 and the other end being adjustably securedunder the grab link 14. WVhen the operator raises the handle 1, theupper end of the chain 11 will be drawn downwardly by means of the grablink 14:, which is secured to the bottom face of the casing 3, and thusa leverage is thereby obtained.

Owing to the length of the handle an enormous leverage can thus beexerted so as to firmly hold the pipe, and after the grip is obtained toturn the pipe. It is to be borne in mind that the lever can be set atany angle or turned in the reverse direction so long as the handle ismoved in such a way as to .draw together any such articles where atightening force is needed, like the putting on of hoops on barrels orto obtain a purchase and hold securely any article of large size and nottoo smooth a surface. It should also be borne in mind that the devicemay be disengaged quickly by releasing the leverage and reset eitherupon the same pipe or upon a larger or smaller pipe by adjusting thechain 11 so as to fit snugly around the article upon which a firm gripis desired.

What is claimed is 1. A wrench of the class described comprising ahandle, said handle provided with a reduced shank, a casing mounted uponsaid shank, said casing provided with a plurality of sockets formed inthe upper face thereof, a chain securing link adjustably mounted withinone of said sockets, a chain secured to said chain securing link, saidcasing provlded with an aperture formed upon the lower face thereof, achain gripping link fitting in said aperture, means for retaining saidgripping link within said aperture, and said chain gripping linkprovided with a chain gripping socket formed in the upper end thereofadapted to receive a link of said chain.

2. A wrench of the class described comprising a handle, a casing securedto said handle, a chain securing link adjustably secured to said casing,said casing provided with an aperture formed therein near one end, saidhandle provided with a socket registering with said aperture, a chaingripping link mounted within said socket, an adjustable plate mountedupon said casing and provided with a longitudinally extending apertureformed therein for permitting said plate to be moved over said apertureformed in said case, and said chain gripping link provided with meansfor engaging a chain and holding the same against longitudinal movementtherethrongh.

In testimony whereof I hereunto allix my signature.
